Older RV fresh water line drain valves can't find style

My 1993 Itasca Sunrise has 5 inline drain valves ..they are grey plastic. PVC ? And they have a pull ring on top that allows the water to drain out thru plastic pipe under rv... To allow normal flow push back down... A couple of mine are allowing leaking onto ground and need to replace..
I have checked at 3 rv stores and no one has ever heard of this type...I have even went to plumbing stores..
Is there a source for these.....or do I need to change the system to another valve.. ?

I am brand new to RV world.. Recent retired...and just bought the RV and have been doing a bit of updating as need..
Glad I found this resource.

I am in Utah ..

    JackUtah, find some that do not require crimp rings. Some use friction fittings you just put in, others use a lock ring you turn on to compress the pipe over a barbed fitting. Look for PEX acceptable fittings.

    they are probable polybutylene and if so they have not been made since your Rv was new. Convert over. If you water lines are grey then it is polybutylene for sure.
